Application filed September a, 1907.

To Cl ZZ whom may concern:

Be it known that I, GEORGE B. HAYNER, a citizen of the United States, residing at Canon City, in thccounty of Fremont and State of Colorado, have invented certain new and useful lin'provon'icnts in lncubntors, of which the foilmving is o specification, reference being hnd therein to the accompanying drn wing.

M invention relates to iznprmIonients in incu ators and heaters therefor and it consists in the novel construction and the combination and arrangement of ports hereinafter described and claimed.

One object of the invention is to provide an improved hot Wetter heater which may be reedily removed from the incubator or breeder to which it is applied, for repairing, cleaning or other purposes.

Another object of the invention is to pro finds an improved means for contrclling'the (dame of the lamp burner of the heater.

A further object of the invention is to improve and simplify the construction and oporation of devices 01' this clnnxwter'cnd thereby render the some more coincnient, reliable and cllicicnt. The above and other objects,-.'/ \ich will appear as the nature ol' the invention is bet ter understood are accomplished in thefpreferred embodimmrt ol' the invention ill rstroted in the accompanying drawings, in Which Figure l is o vertical longitrulinnl section through the incubator and its lumter; Fig. 2 is a perspective view of the heater and one end of the incubator; Fig. 3 is a perspective View of the lhune controlling sleeve; and Fig. 4 is n similar view of the lever for opcrating the some. In the drawings, 1 denotes the body of the incubator which may be of any well known or preferred form and construction and "which has a removable to p or cover 2 adopted to be secured by screws or other fastenings. 111 one end of the body at its top is formed a verticnl slot 3 for illl! reception of the flow and return pipes 1, 5 of the hot water heater wih'ch latter consists of o tank or boiler 6 .and a. plurality of connected pipes Y.

Serial No. 391,344.

Suitnbl secured to the pipes l, 5 of the heater is a supporting plate 8 which is adopted to be fastened by screws or the like upon the slotted end of the body 1 so as to c osc the upper portion of the slot 3. The plnlc 5 serves as :1 means for securing the header in tin incubator and supporting one of its ends. ".lhe other end of the heater wilhinlhc body may be supported by u. bracket .l or in any other suitable manner.

From the foregoing it will be seen that by removing the l'nstcnings for the co ver 2 and the rlotc 8, said ports may be removed from the ody and that when the plate 8 is removed the heater will be removed with it.

Any arrangement of the healing pi cs within the incubator may be employed l iul. the one illustrated in Fig. 1 consists in c.\' tending the llow pipe 4 to the for end oi the body 1 and connecting it lo the center of a cross pipe 10 l'rom'thc ends of which project pipes 11. The latter are connected at their opposite ends by a. cross or end pipe 12 lo lho center of which is connectbd the return pipe 5. The pipes l, communicate with the tank (3 in dil'l'crent horizonlnl planes so us to create :1 circulation of wnlcr through the system of pipes.

The header tank (3 has its bottom l'ormcd with a dome 15} to provide :1. heel rclniniug clnunber 14 into which projwls the upper end of at stationary chimney If). 'lhc hdlcr is supported concentricnlly in (he clnrmhcr H by n pcrl'orztled or :LJHi'lllHil :uznuhu' flange '16 which unites it to the lower purl ol' the bottom of (he lnnl-L, :t cleanly shown in Fig. 1. Upon this lower poi lion ol' (ho holloln oi' the tank is arranged :1v druin rock 17 and upon the top ol' the (:ml-z is :t filling opening or connection lb; provided with it screw cap or other suitable closure.

The numeral 1}] denotes lhc body 01 on oil lamp which has on ordinary burner comprising a wick tube 20 and :1. surrounding lhmgo or support 21 for :L movable chimn y 22. The hunp is supported beneath the tank 6 upon a, bracket having u vrrll portion 23 secured by screws or the like to the body 1 and 2!, horizontal portion 24 having a. seat or recess to receive the body 15) and in which the letter is secured by a set screw 25. The

chimney 22 is adapted to slide within the sta tionary chimney or pipe 15 depending from the tank and it is preferably Constructed of metal and has a sight opening covered by transparent material. Around the lower end of th' chimney section 22 extends a reinforcing wire 26 which has a portion twisted to form a laterally projecting finger piece 27 by means of which the said chimney section may be readily raised and lowered into and out of the section 15 to expose or cover the upper portion of the burner. When the chimney section 22 is lowered it is supported by the flange or portion 21 of the body and when elevated it is supported by engaging the finger piece 27 with a keeper 28 in the form of an angular plate secured to and depending from the chimney section 15. The section 22 is adapted to turn, as well as slide in the section 15 so that by rotating it slightly the finger piece 6 may be engaged with or disengaged from the shoulder or projection upon the keeper, as will be readily understood.

For the purpose of controlling the size of the flame of the lamp burner, I provide a controller sleeve 29 which is adapted to fit around and slide upon the wick tube 20. This controller 29 is formed from a single piece of metal which is suitably cut and bent as shown at Fig. 3 so that its vertical edges are separated to provide in one of its sides a vertical opening 30 which is provided for the purp se of preventing the flame of the lamp from being entirely extinguished when the controller is raised to the limit of its upward movement, as hereinafter described. Projecting outwardly from the opposite sides of the lower end of thecontroller or sleeve 29 are apertured ears 31 adapted to loosely receive the arms of a fork 32 provided upon one end of a lever 33 which has at its other end an enlargement formed in one face with a seat or recess 34. This lever is adapted to extend through and swing in a slot formed in the chimney flange 21 of the burner and is fulcrumed by loosely resting in the forked upper end of a bracket 35 projecting from one side of the lamp body. The seat 34 in the lever is adapted to receive the lower end o an adjustable operating rod 36 which is actuated by a lever 37 suitably l'ulcrumed and jn'ojecting through a slot in the body of the incubator. This lever has its inner end arranged so that it will be actuated by a thermosta't 38 which may be of any suitable form and construction, and the outer end of said lever is apertured to receive the upper threaded end of the rod 36. An adjusting nut 39 is provided upon the threaded portion of said rod for engagement with the lever 37, as clearly shown in the drawings. By means of the nut 39 it will be seen that the flame controlling sleeve 29 may be normally positioned at any desired point upon the wick tube so that as the temperature in the body 1 fluctuates, the lever 37 will be actuated by the thermostat and its movement will be imparted by the rod 36 to the lever 35 and removed from the burner by drawing its end 34 through the slot in the flange 21.

From the foregoing it will be seen that as the controlling sleeve is shifted vertically upon the upper end of the wick tube it-will regulate the size .of the flame so that the water in the heater may be maintained at a constant temperature and that by reason of the slot or opening 30 in said sleeve the flame will not be extinguished even when the sleeve is raised to the limit of its 11 ward movement. The heat arising from the ame of the burner is discharged from the chimney section 15 against the center of the dome 13 and is deflected to the sides of the same, and then passes downwardly and out through the per orations in the flange 16.

Having thus described my invention what I claim and desire to secure by Letters Patcut is The combination with an incubator body having an opening in one of its walls, and a lamp for heating the incubator, of a thermostatically controlled lever )rojectin through the opening in the incu ator an having its outer end apertured, a flame con trolling sleeve slidably mounted on the wick tube of the burner and formed in one side with a vertical opening extending from to to bottom and adapted to admit air to the wic in the wick tube to prevent the lamp from being extinguished when the controlling sleeve is raised to reduce the flame, outwardly projecting apertured cars at o posite points upon the controlling sleeve, a fu crum bracket upon the lamp and provided with a U-sha ed upper end, a removable lever loosely ulcrumed in said U-shaped end of the bracket and having one of its ends bifurcated to provide s paced arms which project through and slide in the apertured ears on said controlling sleeve, the other end of the last mentioned lever being formed with an enlargement having a depression arranged vertically beneath the opening in the first mentioned lever, a

bottom of the outer end of thofirst mentioned lover, substuntmlly as shown and doscnbed. 10

In testimony whereof .I hereunto aflix my Hum 1 signature in p $1 1100 01' two witnesses.
